ABSTRACT

Neurodevelopmental disorders (NDDs) in children, including autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), and learning disabilities, are increasingly prevalent worldwide. Emerging evidence implicates heavy metal exposure—such as lead, mercury, arsenic, and cadmium—as a significant risk factor for these conditions. These metals disrupt neurodevelopment through mechanisms like oxidative stress, neurotransmission interference, mitochondrial dysfunction, and epigenetic modifications. Children are particularly vulnerable due to their developing nervous systems and behavioral exposure patterns. This article explores the epidemiological and mechanistic links between heavy metal exposure and NDDs, highlighting the critical role of nurses in screening, prevention, advocacy, and management. By identifying risks, educating families, and supporting policy initiatives, nurses can play a pivotal role in reducing the burden of heavy metal-related neurodevelopmental disorders and improving child health outcomes.
